What volume tells you
Volume is how many shares, lots or contracts changed hands during a candle. The bars under the chart show it: the taller the bar, the more trading happened in that candle.
Price tells you where the market went. Volume tells you how many people came along. The same 15 dollar rally can happen on quiet volume or on three times the average, and only the second one has real money behind it.
Read it in relative terms, not absolute ones. A 5,000 lot candle is quiet if that hour usually trades 15,000 and unusual if it usually trades 2,000. Always compare against the last few dozen candles.
So volume is not a buy or sell signal on its own. It is a second witness that either backs a move or gives you a reason to doubt it.
How to read volume on a breakout
Breakouts are where it earns its keep. If price clears a high it has failed at for weeks, the breakout candle's volume should be clearly above the average of the last 20 candles. That says the selling above the level was absorbed by real buying.
Then watch the pullback. In a healthy breakout, volume dries up when price comes back to the level for a retest, because few sellers are left. If volume surges again on the retest and the candle closes back below the level, the breakout is in trouble.
Divergence is worth noticing too. If price keeps making new highs while each high comes on less volume, fewer people are joining. That alone is not a reversal, but it is a reason to stop adding blindly.
Invalidation is still set by price: a close back below the broken level. Volume gives you confidence; it does not move your stop.
Try it on a chart
This chart has no volume bars, only price. The question volume tries to answer, whether this breakout is real, has to be read from the candle closes and from where price sits relative to the level.
Price pushed above the previous high; the candle closed above it with a strong body. What's your call?
No sign-up needed. Make your call; when the chart opens you'll see why.
Common beginner mistakes
Treating every tall volume bar as buying. Volume has no direction. A big bar can sit under a candle where buyers won, or under a long-wicked candle where sellers defended a level. Look at where the candle closed, not just the bar.
Comparing different hours. Volume rises every day at the London and New York opens and fades in the Asian session. Compare an afternoon bar with a 3 a.m. bar and you will see a fake surge daily. Compare the same hour across previous days instead.
Waiting on volume and forgetting price. If volume jumped but the candle closed back below the level, the close decides.
Stacking indicators. A volume average, OBV and a volume profile show the same information in different shapes; all three crowd the screen without making the decision clearer. Raw bars plus one average cover most needs.
Where volume misleads
Spot forex has no central exchange, so there is no true total volume. What platforms show is tick volume, a count of how many times price changed in the candle. It usually tracks real activity, but it differs from broker to broker.
Crypto volume is fragmented as well. Each exchange reports its own, a bar that stands out on one may look ordinary on another, and some venues have inflated numbers.
Volume always spikes on news such as rate decisions or jobs data. That spike is the event itself, not confirmation of direction, and the first candle often leaves wicks on both sides. Around holidays volume is thin, and breakouts on those days get reversed more easily.
Finally, you do not know a candle's volume until it closes. A bar that looks huge in the first minutes can end up ordinary, and judging half a candle's volume is as risky as judging half a candle's body.
Frequently asked questions
What does it mean when price falls on rising volume?
It means real participation on the sell side; a broad group is pushing the decline. But a candle at support that closes with a long lower wick on high volume reads differently: sellers traded heavily and price still recovered. That is why volume should always be read together with the candle's close and the level price is sitting at.
Is volume in forex real?
Not exactly. Spot forex does not trade on a central exchange, so nobody knows the total volume. The volume bars on retail platforms are tick volume, counting how often price changed in each candle. It tends to rise and fall with real activity, so it works for comparison, but not as an exact amount. Futures volume gives a more realistic picture.
Is a low-volume breakout fake?
Not always, but it is a good reason for suspicion. Low volume can mean there is little participation to carry the move, and such breakouts get reversed often. When volume is unclear, price still decides: did the candle close beyond the level, and does price hold above it when it comes back? Chasing the breakout candle buys the uncertainty at the worst price.
